Upper limits (95% CL) on the number of DV+electron displaced vertices in 20.3 fb$^{-1}$ and the corresponding vertex-level efficiencies (from Auxiliary Figure 7c) for four RPV SUSY models as a function of the $\tilde{\chi}_1^0$ proper decay distance $c\tau$. The models consider squark or gluino pair production, with masses in GeV as indicated, with either $\tilde{q}\to q[\tilde{\chi}_1^0\to e qq]$ or $\tilde{g}\to qq[\tilde{\chi}_1^0\to e qq]$ decays, respectively.

Upper limits (95% CL) on the number of DV+electron displaced vertices in 20.3 fb$^{-1}$ and the corresponding vertex-level efficiencies (from Auxiliary Figure 7d) for four RPV SUSY models as a function of the $\tilde{\chi}_1^0$ proper decay distance $c\tau$. The models consider squark or gluino pair production, with masses in GeV as indicated, with either $\tilde{q}\to q\tilde{\chi}_1^0$ or $\tilde{g}\to qq\tilde{\chi}_1^0$ decays, respectively.

Details of sparticle decay modes, model parameters, approximate number of generated events $N_{\rm evts}$ and total production cross-section $\sigma$ for selected models considered in this analysis. The long-lived particle (LLP) is the $\tilde{\chi}_1^0$ in all cases except for the model used for DV+$E_T^{miss}$, where it is the $\tilde{g}$. Events in some models are filtered to make better use of computing resources, details are given in the original table and the associated efficiency is already taken into account in the quoted cross-sections.

Upper limits (95% CL) from the DV+$E_T^{miss}$ channel on the production cross-section and the corresponding event-level efficiencies (from Auxiliary Figure 11a) for four RPV SUSY models as a function of the $\tilde{\chi}_1^0$ proper decay distance $c\tau$. The models consider squark or gluino pair production, with masses in GeV as indicated, with either $\tilde{q}\to q[\tilde{\chi}_1^0\to \nu qq]$ or $\tilde{g}\to qq[\tilde{\chi}_1^0\to \nu qq]$ decays, respectively. For comparison, the production cross-sections for $m(\tilde{g})$ = 700 GeV, $m(\tilde{q})$ = 700 GeV and $m(\tilde{q})$ = 1000 GeV are $430\pm80$ fb, $124\pm17$ fb and $11.9\pm1.5$ fb, respectively.
Multi-channel search for squarks and gluinos in root s=7 TeV pp collisions with the ATLAS detector at the LHC
2013
A search for supersymmetric particles in final states with zero, one, and two leptons, with and without jets identified as originating from b-quarks, in 4.7 fb[superscript −1] of √s = 7 TeV pp collisions produced by the Large Hadron Collider and recorded by the ATLAS detector is presented. The search uses a set of variables carrying information on the event kinematics transverse and parallel to the beam line that are sensitive to several topologies expected in supersymmetry. Mutually exclusive final states are defined, allowing a combination of all channels to increase the search sensitivity. No deviation from the Standard Model expectation is observed. Upper limits at 95 % confidence level…
Impact of squark generation mixing on the search for squarks decaying into fermions at LHC
2010
We study the effect of squark generation mixing on squark production and decays at LHC in the Minimal Supersymmetric Standard Model (MSSM). We show that the effect can be very large despite the very strong constraints on quark flavour violation (QFV) from experimental data on B mesons. We find that the two lightest up-type squarks su_{1,2} can have large branching ratios for the decays into 'c-quark + neutralino_1' and 't-quark + neutralino_1' at the same time due to squark generation mixing, leading to QFV signals 'pp -> c bar{t} (t bar{c}) + missing-E_T + X' with a significant rate. The observation of this remarkable signature would provide a powerful test of supersymmetric QFV at LHC.…
